If it goes directly down the drain with the water flowing not a big deal. If you're a bad shot don't do it, use the toilet, that's what toilets are for.
my upstairs toilet doesnt take much more than some piss and one square of tissue but one time i had to shit real bad and so i pooped in the bathtub and tried to break it up and put it down the drain it seemed to work until i took my next shower and ever since then my shower takes like 45 minutes to drain
hey i poop in the shower.i have to take my toes and squish it down the little holes to the drain but it is still easier than getting out drying off and then having to get back in the shower.
Just wash yourself after.
